Have you researched enough about all these items? And searched enough for what you want to do and go with your rig? Piecing a lift together can get tricky at times.
Why do you need a RE isolator?
Are you sure you want RC's Long Arm upgrade? There are a lot of choices and all of them are built differently.
Is the 3.5 RE Leaf spring a full pack?
Boomerang shackles have been dangerous to some and I personally don't like the idea of them at all unless this is only a trail rig. Have you looked into RC's shackle relocators or any other relocators?
Since you will be getting Long Arms I would seriously wait until you put your lift on to wait and see what shocks you really need. Spending money on shocks then having them be your limiter on droop will suck. Just because it says that amount of lift don't mean that it will fit your needs.
Have you looked into a WJ knuckle swap to OTK to save some money?
Don't see a reason in the HD LCA mounts unless yours are all tore up and need replacing.

One thing you are forgetting is an SYE and driveshaft. Gonna need those if you are running boomerang shackles. Probably gonna need some leaf degree shims too.
Longer sway sway bar links?

Seems like you got most of the parts needed but left out a very important one(SYE) and one safety precaution item(sway bar links).

do WJ knuckles, better steering options and bigger brakes. i have em and love it! stops better than stock. and it works with stock steering so if your in a bind u can use it. i wouldnt go with RC long arms, if your going long arm do a long arm and not radius arm.

I'm still researching the WJ swap.

Any suggestions for long arm setup? I've only really looked at radius since nearly everyone runs them.

I dont like the rough country long arm kit, mounts hang awfully low. For a radius arm I think TNT is the best (what I run as well). Stacked hokey pucks work as cheap and good front bumpstops. I welded a nut to the center of the spring pad to bolt them down.

I'm gonna just save my pennies for a BDS lift. I've always wanted one, just never could justify the price until.

Front brake lines from a 95 gm 1500 will work and give you about 5" more slack. Only have to gring the caliper steel line a bit to mount. You'll know what I mean when you go to do it, takes 5 minutes and the lines are only about $20. Easy to get new ones on the road if you tear it. My XJ has Rustys LCA with heim joints at one end. THey havn't let me down yet and i can flex like crazy with just the stock mount location. I'm talking tire under the body line and spring is unseated
